No longer sane...I can identify with you. I felt so much the same when I was in my teens. It took me until my early 20's to get real help and by then it had gone on for far too long. I didn't get help because my father also didn't believe that depression was real and he felt that time heals all. I ended up seeing a psychiatrist on my own and I was put on meds and I wound up keeping it a secret for years. My family knows now and they know about the relapse that I'm experiencing now too. My relationship with them has fundamentally changed, but that's because of the confidence I have because I got healthy. (Too bad I couldn't stay that way...)

Do what YOU need to do to get healthy. Right now, you need to be the most important person in your life. You can love your family, but you have to put yourself first. If you have to do it on your own, do it!!! Know this...you are NOT weak because you are depressed and you are NOT stupid because you can't cope. You are just going through a difficult time like everyone else on this site and like all of us, you need to take a time-out and get the support you need to get healthy again.
